I heard some data scientists say why they prefer Python to other languages, "one do not need to learn Python, you can just code in it". Those data scientists (I'm talking about) are former mathematicians and physicists, they have weak computer science background and do not wish to waste time digging into how it works on implementation level, learning new syntax, thinking about type correctness. I'm not sure that they will refuse Python without strong force of circumstance. But I think there will be some number of kotlinhead data scientists who will use Kotlin for data science 😏
